Dont Forget the Seeds:

Roasting the pumpkin seeds after carving the Halloween pumpkin is a tradition, but you can carry that tradition over to any member of the winter squash family. Preheat oven to 350 degree F. Rinse the seeds under running water to clean off attached pulp. Shake off excess water; spread seeds in a single layer on a lightly greased baking sheet. Lightly sprinkle with salt or other dried seasonings, then bake for 15 minutes or till browned. Roasted squash seeds make an excellent high-protein snack.
